modify mysql php query results prior to returning

Question

I have a database with a table containing user information.

User table: id username password

When the user table is created, I also create a table for each user named after the id. id table: req_id (auto increments) vendor authorized

I am querying the user table and also want to query the newest req_id for each user and return the results. I have to append each row of the results with the users req_id

I have the following code but am not sure on how add the req_id to each row and return the results.

public function getAllUsersInfo() {
    $result = mysql_query("select * FROM users");
while ($row = mysql_fetch_assoc($result)) { 
        $rows[] = $row; 
} 
for($i=0;$i<count($rows);$i++) { 
        $id = $rows[$i]['id']
    $req_id = mysql_query("select req_id FROM $id ORDER BY req_id DESC LIMIT 1;");
//Need to append the req_id to the row
} 
    return $result; //so should be returning id, username, password, req_id
}

<?php

public function getAllUsersInfo() {
    $result = mysql_query("select * FROM users");
    while ($row = mysql_fetch_assoc($result)) { 
        $rows[] = $row; 
    } 
    for($i=0;$i<count($rows);$i++) { 
        $id = $rows[$i]['id'];
        $req_result = mysql_query("select req_id FROM $id ORDER BY req_id DESC LIMIT 1;");
        $req_row = mysql_fetch_assoc($req_result);
        $rows[$i]['req_id'] = $req_row['req_id']; // Add the req_id to the row
    } 
    return $rows;
}
